IMPROVEMENT N' OILEIRS.`

The Bche'dule referred to in these Letters Patent and making part of the same.

To all whom it may concernl Be it known that I, JAMEs A. METCALF, of Lawrence, in the county of' Essex,'and State of Massa chnsetts, have invented a new and useful Improvement in Oil-Can 'l.ubes, and similar tubes of other vessels and I do hereby declare that the following is a full, clear, and. exact description thereof, reference being had to the accompanying drawings, and to the letters ot' reference marked thereon.

Figure 1 represents an elevation of' an oil-can.

Figure 2, a section of a tube of my construction.

Figure 3, a section of a tube yas now made, having a plug of my construction inserted in its wide lower end.

Figure 4 represents asectiou of a tube, which has become worthless, by enlarging or rimming out its vent.

VFigure 5, an elevation and section of a plug.

My invention relates to an improvement in the tubes or discharge-pipes of oil-cans, and such other vessels, where similar tubes are employed; and consists iu placing the vent or orilice which regulates the amount of oil discharged in the wide lower end of the tubes.

'lfhetubes as at present constructed, allow of hav-v as clearly shown in fig. 2 of the drawings, or to insert plugs in the. wide lower end of tubes as now made, as

shown in figs. 3 and 4 of the drawings.

In this construction, the vent is in the lower end of the tubes, the end of which is screwed into the oilcan, and the vent cannot be tampered with so easily, and tubes will not become worthless by having their small end bruised, broken oil', .oi rimmed out.

In lig. 2, the plug, with the vent, forms the lower end of the tube, which is screwed into the neck of the can,

The plugs may be made of any suitable, metal and any suitable shape, and nia-y be either screwed into or solderedin the wide end of the tubes.

I propose to countersink both ends of the plugs, so that'a tube maybe easily cleaned out, iu case any dirt should get in, by running a wire through it.

` Having thus described my invention,

What I claim, and desire to secure by Letters Patent, is-

An attachment to oil-can tubes, or similar tubes of other vessels, consisting of a metallic plug, with, a

vent-hole, such plug forming, or inserted in the wide lower end of such tubes, substantially as and for the purpose set' forth.

ln testimony whereof, I have signed my name to v thisxspecification, in the presence of two subscribing witnesses.

JAMES A. METCALF.
